Rigify pose Issue Mesh Deforming on knee
Thanks for the support Candice babe. But I finally figured it out! Woo Hoo!

Alright so I figured out that my Z Axis in the legs were facing the wrong direction of the Original Human Meta Rig Armature.

So then I was like, That looks wrong. I fixed it but I still had an Issue.

But Then I finally figured out I had to fix the Z Axis of my Foot's Roll. Makes perfect Sense.

So all in all for those of you with this issue.
Look for your armature's Foot IK (Which should be that little bone sticking out from the back of your foot) Find that, click it and press N to open your Window.
Next! Scroll to the top in that window and find Roll.
Change the Z Roll till it's pointing Downwards/Backwards and Bam! You got it fixed.

Tip: Now if you want to make a Horseman Just make your Roll face towards the front or   The Opposite Direction.
